INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed November 1906. Serial No. 342,415.

' State of Pennsylvania, have made a new and useful Invention in Internal-Combustion Engines, of which the following is a .specification.

This invention'relates to internal combus' tion engines and more particularly to pistons for such enginesl,

An object of this invention is the production of a piston in which simple and "effective means are utilized forintroducing into the piston a cooling liquid and causing it to circulate therethrough. This and other objects I attain in a piston embodying the features herein described and illustrated. 1,

- In theidrawings accompanying this application and forming a part thereof, Figure 1 is a longitudinal sectional elevation of a piston embodying my invention; Fig. 2- is an end view of the piston shown in Fig. 1; Figs. 3 and 4 are, respectively, plan and side elevations of a 'detail embodying my invention;

and, Fig. 5 'is' a sectional elevation of. the piston showing a portion of the-piston rod and the arrangement of the cooling liquid passages.

The piston is cast with an interior charm her 6 and openings-7' and 8 arranged at either side, through which a piston rod 9 7 extends.

provided at either side with openings 12,- which communicate with the intcriorpham The piston rod is hollow and is ber 6. Each. of the openings 12 'isprovided with nozzle portions 13, which are located within the chamber-6 and are secured between the rod 9. and-a-rentrant flange 14,

formedintegrally" with the wallsof the piston. I

Eachno'zzle 13 comprises a base portion 15, which is constructed to fit snugly against the peripheral face of-the rod, and -a radially-extending ortion 16provided with a passage 17. whic' communicates with one of the openings 12 of the rod.

Two sets of'lugs 18 are formed on the flange 1 1 and are located diametrically oppo- .s1te each other on either side of't-he openings I and 8. The lugs 18 cooperate with lugs 19, formedon the base portion 15 at either side of the portion 16 to holdthe nozzle portion circumferential-Ly in" place on I the rod. I

xA 'partition or diaphragm 21 issecured in place in the passage formed through the rod 9 by a pin 22 and is so arranged that the passage through the rod is dividcd'into two parts; one part communicates with the chamher 6 through the passage 17 of one of the nozzles 13 and the other communicates with the chamber 6 through the passage formed inthe other nozzle. Under such conditions the water enterin the chamber 6 first traverses a portion 0' the passage through the rod 9 and is delivered to the chamber 6 13. The water passing through the chamber divides and flows on either sideof the rod and is discharged fromthe chamber through the upwardly-extending nozzle and com-- municating passage ofthe pistonrod. In assembling the piston and piston rod,

the nozzles 13, which are of such size that they may be readily introduced into the chamber 6 through the holes 7 or are set in place between the holding lugs 18 and the piston rod is then forced into place. The rod is provided 'at one side of the piston with an integr ally formed collar 23 and at the other side with a'screw thread 2 1. A nut 25,..screwed onto the threads 24:, forces the piston in place on, the rod against the collar 23 and thereby locks the nozzles'13 in place within' the chamber 6. .VVith such an arrangement the casting of the piston is greatly simplified; no complicated coring is necessary and means for ail-adequate circulation of the cooling li uid is also obtained.

In accordance with t e provisions of the patent, statutes, I have described the prin- 'ciples ofoperation of my invention, together wlththe a paratus which Inow consider to paratus shown is only illustrative and that the invention'can-be carried out by other means.

'What I claim is: I

1. The combination of a hollow piston rod havingradialopenings, a hollow piston on said rod and having openings registering with those in'the piston rod, a partition plug in the piston rod and provided with ports leading into and from the piston and removable nozzles in the piston, said nozzles being held in position between the walls of the piston rod and the piston.

2. The combination of a hollow piston rod represent tie best embodiment thereof; but. I desire to have it understood that the apthrough the downwardly-extending nozzle having radial ports, a ported partition plug in the piston rod and communicating with the ports in the-piston rod, said plug being so positioned that fluid flowing in from one end of the piston rod will be directed through the ports in the plug and in the piston rod and whereby fluid passing through ports in' the piston rod and plug may be directed out through the opposite end of the piston rod, a hollow piston on the piston rod, nozzles in the piston and having base flanges removably seated in recesses in the piston, said nozzles registering with ports in the plug.

3. The combination of a hollow piston rod ARTH UR J. WEST.
